First I’m super sorry for the top post, I’m at plumbers and I forgot to upload my muttrc to my new cloud instance, so I’m screwed using outlook.
I have a completely untested, uncompiled patch that I think will fix the problem, would you mind giving it a go?

The libvirt team reduced this to the attached test case run as follows: In a separate terminal, qemu-kvm -vnc 127.0.0.1:0 to grab port 5900. Then do this: $ gcc bind-collision.c && ./a.out bind: Address already in use AF_INET check failed. $ gcc -D CHECK_IPV6 bind-collision.c && ./a.out AF_INET6 success AF_INET success $ gcc bind-collision.c && ./a.out AF_INET success Bisection showed this behavior to be caused by commit 319554f284dda9f2737d09df82ba3610bd8ddea3 Author: Josef Bacik <jba...@fb.com> Date: Thu Jan 19 17:47:46 2017 -0500 inet: don't use sk_v6_rcv_saddr directly When comparing two sockets we need to use inet6_rcv_saddr so we get a NULL sk_v6_rcv_saddr if the socket isn't AF_INET6, otherwise our comparison function can be wrong.
